Getting Started with x64 Assembly

8 August 2021 assembly linux

A while ago I decided the learn the basics of the Assembly language for my x64 processor. Assembly has a reputation for being difficult and elitist which is keeping many people from trying it out. But once you learn the basics, it is actually really simple. In fact, in many ways it is much simpler than other programming languages. Using Linux as our host system, we can make system calls to the kernel for many operations like reading and writing standard input/output and files. Also the x86 instruction set allows us to perform string operations and "loops" directly with a single instruction, condensing many common operations into just a few lines of code.
